Abstract Electrochemical water splitting for hydrogen production has sparked intensive interests because it provides a new approach sustainable energy resources and the avoidance of environmental problems. The precious metal‐based single atomic catalysts (PMSACs) have been widely employed in catalysis by virtue their maximum atom utilization unique electronic structure, which can reduce metal amounts remain high catalytic performance simultaneously. In this review, we will summarize recent research efforts toward developing SACs based on metals with excellent electrochemical catalysis. First, synthesis strategies PMSACs be classified introduced including high‐temperature pyrolysis, method, photochemical reduction, wet chemistry etc. Then, short description characterization techniques given, mainly involves aberration‐corrected scanning‐transmission electron microscopy (AC‐STEM) X‐ray absorption spectroscopy (XAS). particular, relationship between structure sites discussed according to theoretical experimental results. Finally, brief perspective provided highlight challenges opportunities development novel suitable applications.
